[origin: EP0878214A2] A process to remedy a polluted medium includes contacting a first medium containing a pollutant with a second medium containing a microorganism which is capable of decomposing the pollutant. A membrane permeable to the pollutant and impermeable to the microorganism is spaced between the first and second media. The first medium and the second medium may flow in opposite directions to each other. <IMAGE>
